Yes...I cannot figure out if I'm a Five or a Nine.
I've always tested Five. And watching some of the Enneagram videos on this forum definitely makes me think I'm a Five.
On the other hand, I don't Disintegrate towards Seven and I don't think I Integrate towards Eight. I Disintegrate towards Six--worrying, catastrophizing, second-guessing, prioritizing safety/security. And I Integrate more towards Three--feeling like, hey, it really is worth it to put on some lipstick and maybe a pretty scarf before leaving the house! That kind of thing.
So on that basis, I've concluded that I have to be an atypical Nine. And yet...the videos on this forum...the only area where I relate to the Nines is their gentle hands and low-energy affect. Otherwise, I fit in a lot more with the hyper-verbal, idea-machine-gun Fives.
